I have the same feeling about this law as I have about Donald Trump. Even though you know it's bad, there's a teensy-weensy part of you that likes the fact that it's sticking it to Saudi Arabia and the political class that's trying to defend Saudi Arabia even though it's pretty clear those shitbags are pretty much behind 911.
Also there's a part of me that thinks maybe it would be a good thing if there was more at stake when we blow up wedding parties with robotic death machines and the like.
Buying the president's defense is a lot like buying Hillary's defense of NAFTA. Maybe that plays well to policy wonks, but regular people aren't buying it and don't appreciate politicians trying to tell us white is black in the name of "American interests" or "national security."
